Step 1: Step One: The Basics

The great thing about going as the They Live aliens is that since they're posing as normal people, you can wear your regular clothes! There are a few things to do though to make your costume more distinctive

While technically you can wear whatever you'd like, tying in the subliminal imagery/ messages from the movie into your outfit really adds to your costume. Get a plain white t-shirt and some iron on transfer paper. Then simply pick some of the subliminal words from the movie to put on your shirt. Here are some of the options (but you can create your own): Reproduce, Consume, Obey, Conform. A shopping bag with the word BUY on it will also add to the feel of the costume.

Because of the way the masks will sit on your face, chances are you'll need wigs as well (unless you have bangs) and don't forget to paint your exposed skin blue with red patch accents to match your mask.
